The operator of Papua New Guinea's major Liquefied Natural Gas Project says information it has about an incident at one of its sites in which a worker died indicates gunfire was not the cause of death.
Reports emerging online from people claiming to be witnesses to Tuesday's incident say police officers became involved in a confrontation with two project workers at the Tamadegi camp in Southern Highlands before opening fire and killing one of the workers.
The other worker reportedly sustained a bullet graze on his head.
The project operator, Esso Highlands Ltd, says it understands a man died but that the cause of death is not known.
A spokesperson for Esso says it's also unknown whether the death was related to a reported breach of security at the Tamadegi area camp operated by pipeline contractor Spiecapag.
Esso says an investigation is underway
Work has been temporarily suspended in the Tamadegi area and there is some damage to camp facilities.
